发明名称 METHOD FOR DETECTING AND WARNING AGAINST WRONG-WAY DRIVERS, AND WRONG-WAY DRIVER REPORTING AND WARNING SYSTEM
摘要 The present invention relates to a method for detecting and warning against wrong-way drivers, the method comprising the following steps: a) establishing a radio field over a roadway section to be monitored and at least substantially transversely to a predetermined correct driving direction of the roadway section, the radio field having at least two radio field sections that are spaced apart when viewed in the driving direction and have associated reception field strengths; b) detecting attenuations of the reception field strengths of the radio field sections that occur due to radio shadowing during driving through the roadway section; c) determining the sequence of the radio field sections in which an attenuation of the respectively associated reception field strengths has been detected; d) comparing the determined attenuation sequence with the correct driving direction; and e) initiating at least one warning signal if the attenuation sequence runs opposite to the correct driving direction.
